Indicator with alert.

["Bernie" <eurobernie@xxxxxx>]

Hello friends.

I use asctrend and I include an alert with this:

if checkalert then alert = TRUE;

The indicator alerts me when the bars is always red or blue but I need that
the indicator only alert me when change the color:
Exemple:
    1-Alert when change from red to blue.
    2-Alert when change from blue to red.
    3-Donīt alert when change from red to red.
    4-Donīt alert when change from blue to blue.

If I use ( if checkalert then alert = TRUE;) only alert me in option 3 and
4.

Thank you.
